Purging requisition data from requisition interface tables

Summary:

There doesn't seem to be a way of purging data from the requisition interface tables.

Content (please ensure you mask any confidential information):

We have over 871,000 records and rising which cannot be purged. All other areas can be purged, i.e. AP, GL, PO, Receiving etc, however there is no way to purge requisitions. This was raised here in 2019 (Idea Number 499539) where it received 88 votes, 57 of which were unique, yet was updated to say this was not pursued due to it receiving limited community voting (how many votes more did this need to be supported?).

Please can this be looked in to and advise why every other application can be purged, yet requisitions cannot. Surely this should be something that was available from the beginning and standard functionality.
