Best way to translate these through holes across the length of this rail? CATIA V5

What's the best way to get these holes to translate across this extra length I have on my rail? I can't access the actual sketch of the hole as this was imported as a STEP file (the model is acting as one solid sketch).

Any help would be appreciated, thanks!

Select the surfaces of the slot, use the Rectangular Pattern tool to copy as many as you want. Another way would be create a new sketch on the slot surface, pattern and extrude it.
