Hi @Max_Murphy - does this work for you?:
Define a “services” table which links services to teams:
Then in your main table set up Service as a linked record and Team as a lookup on the services table:
Now, when you select the Service you want to the Team field is automatically populated.
I’m not sure if this works with the API, i.e. if you populate “Service” using Zapier does the team get populated automatically (and I can’t test this now), but worth trying.
