I assume that strip is 8 equal size frames. If so, save it as a .bmp, load animation and load that .bmp.
Then Promotion will ask you how many rows and columns it has, which would be 1 row, 8 columns here if my medicated head is not fucking up the calculation.
This should result in a 8 frame anim using the same palette.
Only works in fullversion too I think.
