Allow subscription type management through properties

Hi there,

We’d like to allow our sales team to change subscription type opt-in/outs through changes in properties (I’m aware that this is not the intention of the subscription type tool) that then should be mirrored to the subscription types. Equally, subscription type changes can be triggered by form submissions and should then be mirrored to the custom properties for the respecting subscription type. 

We’ve created a system of properties, workflows and lists that manages this quite well but there are still 10% of use cases where the setup doesn’t work. E.g. as subscription type triggers in workflows don’t allow re-enrollment. 

I was wondering if anyone in the community has created a similar setup created and is willing to share the concept/logic?
