How to manipulate value in Dat section

In a DAT area, the following are listed, they represent bitmaps for the numbers 1 through 0 and are used on an LCD screen similar to a VGA display. I cannot just print the numbers using PRINT(x), since the LCD is flipped on edge 90 degrees. So I flipped the numbers and made new bitmaps, exported as .dat.
The program is out of memory using BST optimized and deleting unused. There is more work to be done so I am looking to cut the memory wherever possible. One area is below, where I need to display 4 digits across the LCD using bitmaps. All I could come up with was to use the same .dat files and just place them at different spacings along the Y. So if the number is 1234, the 1 is at y=14, the 2 is at y=10, etc. This is wasting space in DAT. So the question is, how can I call up these graphics_info bytes and modify the y number and therefore use only one section versus 4 copies?
Next question is, what options exist to park a lot of bitmaps that are called up as needed? SD card? And, can the SD card be accessed to read a la carte dat files?
Can these graphics_info bytes be move to VAR, and I could just simply modify them on the fly prior to each use? If so, I would appreciate an example of how these bytes would be translated to VAR.
Thanks.
