Not enough E's in machine!! G92, G53, G10 what?

OOPS, I meant G52 in the title..

I need to tap into the vast knowledge base of the FADAL guru wizards here...

I produce with my FADALs over 50,000 steel parts on our 4th axis machine per year. 1st phase is in a 4th axis fixture I built to hold 64 parts(16 pcs at 12, 3, 6 , 9 o'clock). 2nd phase is done in 2 EMC's of ours that cut a dovetail on the bottom side with self-made dovetail tools(steel is mine, mitsu 60' inserts). I have programmed the 4th axis 4020 with G54 being the A0 position, G55 being the A90 and G56 being the A270 for a z height of 10 mm's above my vice. Then G57, G58, and G59 for 13mm family of parts and so on. All parts can be made without EVER changing my work offset table.

Trying to do the same with my EMC setup. Fixture holds two rows of 12 parts across the table, 24 total. Spacing is 36mm's between parts on X-axis. I want to have a programming system where I can have "dedicated positioning" either within the work offset table or beginning of program that has both X and Y info but also Z info(I zero tools off of LED height block gage.) Problem using E1-E48 is I have more different parts and programs than I have E numbers(48 pcs.) I would rather not use G92 in beginning of program because we have to start mid program alot when testing programs. Right now I use G92 to do my 36mm spacing, any better ways(less prone to startup errors not taking G92 off)

Basically every program would need two work zeros, one for each row of 12-and a total of maybe 50 programs.

I know I can write a note in beginning of every program to tell user what G54 and G55 he should write in work offset page, but there has to be a better way!!!!

The G92 is difficult to work with. I would use a master "E" fixture offset and then move from part to part with a G52. This shifts the part zero position INCREMENTALL from the original "E" fixture position. When you are finishe simply code "G52 X0 Y0" and you'll returen to the master "E" code position.
