Using iteration block on multi-rate system

I was provided a system composed of multiple subsystems operating at different sampling rates. Because my simulation runs at 100 Hz and the provided multi-rate subsystem runs at 200 Hz (composed of s-functions that I cannot alter) I want to loop the entire subsystem twice in order to incorporate the subsystem.

The error I'm receiving is "Only constant (inf) or inherited (-1) sample times are allowed in iterator subsystems".

Issue related to (hard-coded?) sample time of the S-function I guess.

Can't you just increase the sample rate of the input signal(s) to the subsystem using a rate transition block ?
