Switch groups on and off in CSM

I have some springs I need from phase 1 to 10 where I want to switch them off.

Right now I have the following syntax which I think is rather clunky:

CS NO 1 TITL 'Start'
GRP NO 14 ATIL 10

I would prefer to be able to switch it on and off using a syntax similar to this instead:

CS NO 1 TITL 'Start'
GRP NO 14
...
a bunch of intermediate steps
...
CS NO 10 TITL 'End'
GRP NO 14 VAL OFF

Is this in any way possible?

No this is not possible as it is against the main principle of CSM input. The input CS and GRP are independent of each other.

Usually the CSM input follows three steps of input with individual and independent input lines.
1st table defines the stages → CS
2nd table defines the groups —> GRP
3rd table defines the load cases → LC

Have a nice day
