Update formulas in Excel by increments of 1 when copy/pasting with several cells in between

I'm looking to make work easier for myself by copy/pasting Excel formulas. This is usually no issue for me, but on this particular worksheet, there are several cells in between what I'm pasting.

What Excel is doing:

Taking formula
=IF(SolData!B40 = "[VACANT]", "MTOE SLOT NOT ASSIGNED", SolData!B40)
from A1 and pasting it in A10 gives me
=IF(SolData!B50 = "[VACANT]", "MTOE SLOT NOT ASSIGNED", SolData!B50)

What I want to do:

Take formula
=IF(SolData!B40 = "[VACANT]", "MTOE SLOT NOT ASSIGNED", SolData!B40)
from A1 and paste it in A10 giving me
=IF(SolData!B41 = "[VACANT]", "MTOE SLOT NOT ASSIGNED", SolData!B41)

Any insight? I'm not an Excel noob, but I'm no guru either.
