Retain input buffer from fields when QINACTITV kicks user from session. CPI1127&PSSR

I'm still kinda new to the RPG space, and I guess it's time I actually post
a question as my research has not led me to a working result yet.

My shop has a strict 20 minute timeout setting for the workstations. This
cannot be changed. Workstations (which have static, unique names) are being
kicked (the job is ended, not disconnected) and users are losing input
data. The system kicks out a CPI1127 when this happens. They are typing
lengthy entries and/or get distracted by phone calls, co-workers, etc.
Since they do not press any function keys, rollup/down, or Enter during the
time limit, their entries are lost when the system kicks them. (Note: they
are being given ten 70 length fields to enter data in the program affected
by this timeout setting.)

I was hoping the PSSR can trap the error was have the input field written
out to a work file. A CL program will be needed to check in there is any
data out in the workfile when the resume the program. This workfile could
be cleared each night after hours to avoid left over data. The problem I'm
running into is that even after coding a PSSR routine in the program, it
isn't executed when the system ends the job. The CPI1127 message can be
found in the QSYSOPR queue, but the PSSR doesn't seem to catch this.

Here is a sample program I wrote to test that theory. The program should
write to the XT90 file unless an error occured, then it will write to XT91
instead.

Am I barking up the wrong tree with PSSR and MONITOR? Thanks in advance.
