No. The Thru port is only for directly copying the data arriving at the In DIN port - you can also change the Hardware port function into a Din Sync port but that’s not relevant here
.
If Rytm is master clock then you need to find another thru port further down the midi chain or a thru box or use audio sync etc - or get a din sync to midi or audio sync gadget … or possibly make one with an arduino etc
.
a simple mid thru box may be simplest just after the rytm if you can’t find another midi output containing the master clock
