REDCap Question – is there a way to link a specific subject (record ID) between different arms?

Like the title says, is there a way to link a specific subject (record ID) between 3 different arms? For example, let’s say I have a randomization arm, a treatment arm, and a control arm, is there a way to link the subject’s data in the randomization arm to whichever arm they were randomized to (treatment or control)? I’m mostly looking for a way to pipe data entered in the randomization arm into instruments within the treatment/control arm for the same subject. Thanks in advance!
