This sounds like a use for Flash tables. If you've got an 18F or later,
tables have their own instructions

For example, to retrieve a byte from an 18F table, where "t_base" is
a 24-bit address

         mov     upper(t_base),tblptru ;table base address <23:16>
         mov     high(t_base),tblptrh ;table base address <15:8>
         mov     low(t_base),tblptrl ;table base address <7:0>
         tblrd*+               ;read, increment pointer
         movff   tablat,temp   ;retrieve data from address, copy to temp

tblptrx can have W added to them. It's all in the datasheet

If you have something like the 16F, a table stored in Flash can be
accessed with eecon1,eepgd set, target address in eeadr and eeadrh
and data in eedata and eedath. Note that for the 16F it's one byte
of 14-bits, for the 18F it's 2 bytes of 8-bits

Bob, despite the Subject, Jason didn't actually mention shutting
down !!! Had me wondering there for a sec
