Frequency response analysis - excite multiple nodes

Hello --

When I set up a frequency response analysis by "Edit analysis parameters > Analysis setup > Excited nodes tab" I would like to be able to input multiple nodes into the "Node number of applied excitation" field. I realize that I can do this by adding a new node set for each new node. However, if I have a large number of nodes that I want to excite (perhaps corresponding to an entire surface) then this is very tedious and time consuming. I have tried pasting a list of nodes but this doesn't work.

If this can't be done within FEMPRO, can it be done by directly editing a FEMPRO file? If so, how?

Note: all loads have the same frequency, direction, phase, and force or acceleration.
