GRM Tools Classic not completely automatable

[rs_ml]

I'm using GRM Tools Freeze in Tracktion 2 demo,
as I'm still not sure which host I should settle
and can't automate the freeze button there.

It isn't listed or recorded, but definately an
parameter, which comes up in other hosts...

Any ideas? Thanks in advance, RS

Nobody has a comment? As Steinberg isn't responsible for
GRM anymore and I can't afford an upgrade I would like to
know, if there is a tweak.
