Can I assign different transient solution steps to different physical fields simultaneously?

Hello everyone, I would like to ask you a question, can I assign different steps to different physical fields simultaneously?
I'm doing a simulation of a lithium-ion battery where the electrochemical field state changes very quickly, so it takes steps as small as 1 second. However, the change of the thermal field is relatively slow (because the propagation time of temperature is slow), so I think it is not necessary to use the step size of 1 second for the thermal field, but about 10 seconds, so as to reduce the calculation time. It should be noted that in a battery, the electrochemical and thermal fields are coupled to each other.
In short, the steps I expect to solve are (please see my attached graph):
1s: Electrochemical field solving →2s: Electrochemical field solving →... →10s: Electrochemical field and thermal field solving →11s: Electrochemical field solving →...→20s: Electrochemical field and thermal field solving→...
Can I do this in the powerful COMSOL? Thank you!!
