 I realized another way to do this. I have a program which collects
 ready made sub pcb files for a subpage. See:
 
 https://www.delorie.com/archives/browse.cgi?p=geda-user/2022/11/06/03:11:40
 https://www.delorie.com/archives/browse.cgi?p=geda-user/2023/03/14/19:50:18

 It takes ready made sub pcb files for a design and prepends the
 source syms refdes value to the contained elements and writes that
 out to the current directory, one file per source symbol.
 I could update that program to also change an elements
 value and solve your case in that way.

 That wouldn't help with bom files, but it makes it esier to make
 a pcb design with many sub pages/subpcbs. It expects the sub pcb files
 to be in the same dir and have the same base name as the sub sch file.
 Since I mostly do two layer pcbs, it also produces an upside down
 version of each subpcb.

 Run it on the top sch file, start a new pcb with your desired
 dimensions, for each collected sub pcb file "add layout" and
 place the buffer. Then when all sub pcbs are placed, run e.g.
 lepton-sch2pcb and complete the pcb.
