Use Program Member Custom Fields to Change Program Status
Hi
I'm running a few events using Marketo I'm wondering if we could use Program Member Data could change Program Status? Does anyone have experience doing this?
We plan to promote the events on social media, emails and the like and there are a few of them running simultaneously.
Essentially the user will fill out a form:

In the form there are hidden fields:

I've gone ahead and created custom program member data and was hoping that in my flow step once someone fills out the form from Linkedin they would be placed in Waitlisted status.
Unfortunately, I can't pull the Custom Program Member Field "Campaign Name" but can pull a custom field UTM Campaign Name.

I thought using the Custom field wouldn't be a problem, but we plan to promote a few events running simultaneously this would result in the fields being overwritten on the contact records.
Is there any way this can be done?
