How to define a moving spring (mobile load) in +PROG SOFIMSHC?

I’m setting up an analysis of a pedestrian bridge subjected to a moving pedestrian load.

In the example provided, the spring is defined using +PROG SOFIMSHA like this:

GRP 99
  SPRI NO 99003 NA 10001 DZ 1 CP 1E3 CT 0.01 // contact moving spring
  BEAM NO 99 NA 10001 NE 10002 NCS 99 // for graphical animation - GAM=0.0
  NODE NO 10002 fix MM

However, I would like to perform the same analysis using +PROG SOFIMSHC instead.

How can I define a moving spring in +PROG SOFIMSHC?

If you only need SOFIMSHC for geometry creation you can do it in SOFIMSHC and then define moving spring in separate SOFIMSHA module. Just remember to put SYST REST after the head line.
