How to automatically reset monthly credits to Memberstack users in a Webflow AI service despite Make.com's user list restrictions?

Hi, Julian Galluzzo Duncan Hamra Thank you for the fantastic templates and tutorials. I have a maybe more advanced question.

I'm working on a subscription model with credits with webflow, make and memberstack. It's a website where you can use an AI and credits are billed depending on the intensity of use. You can also buy credits in addition to the subscription. I've actually set up everything with Make.com and it's  working.

To be honest, the only problem is the monthly subscription. I can't find a way to update the credits (stored as metadata in Memberstack) on a monthly basis. So that, for example, 300 credits are always allocated to each user on the 1st of the month. Is there any way to do this? Doing this manually would be quite time consuming if you have a few more users. I can't find a way via Make either. I thought you could set a monthly trigger that updates all members of a plan. However, the "List" module in Make is limited to 100 users, so this is not possible. 

I have watched the video tutorial on the credit system, it is very good, but does not give an answer to monthly credit distributions either. 

Do you already know a way to trigger the monthly update of the metadata? That would be fantastic.
