Batch Delete of Transactions

I want to be able to select 10 or 15 transaction at a time and delete them from a student's account. Our last season was very messy between COVID and it being our first season using DSP, and I want to wipe off everything that took place before this season. On second thought, even just a setting that would allow us to make all transactions before a certian date invisible unless the setting is off would be just as useful.
