Yep – a point many of us have made repeatedly on this forum. Before daily Mass is the obvious solution, which many parishes do offer. When a parish will never offer pre-Mass confessions (I mean a parish with at least one full-time pastor, let alone 2 or 3), then it seems that it is not a priority for the parish in question.
I was recently involved with a parish in which the priest “couldn’t figure out” what to do to increase regular attendance/involvement. So, at a large meeting suggested by him, the parishioners told him (I was there): the church itself open more often for prayer, and
frequent confession. We all provided a number of options for both requests, including collaborating on staggered confession times and open churches with other nearby parishes in the diocese, and publishing those. (So as not to overly burden any one pastor or parish.)
The pastor was completely non-responsive, despite the parishioners pleading with him. Confession is still only the one hour before Saturday Vigil Mass.
I’m quite sure that hearing confessions is draining, or certainly can be. Here’s a solution, if you don’t want to hear confessions, don’t become part of the Roman Catholic ministerial priesthood; instead, find another role, such as an Order, a function, a location in which not ministering to a parish is a possibility. That’s why many men become Brothers instead of priests, and other men join contemplative orders, and still others don’t get ordained at all but teach in Catholic locations without Holy Orders. The main function of the ministerial priesthood is administering the sacraments. I am not commenting on the particulars of the OP’s situation; the meeting may have indeed been an emergency, not to mention confidential in nature & sensitive – just commenting on the above poster’s remarks.
I don’t expect all parishes to have the same focus as my local parish does, which is Sacraments
in Extremus 
. (Multiple times a day, every day of the year) But except for truly understaffed situations, such as rural parishes and other exceptions, it is difficult to believe that where’s a will, there is not a way, within any dioceses that are dense enough to have some kind of cooperative scheduling with other parishes. Even 2-3 times a week, within a narrow geographical range, would be a vast improvement.
