When creating a payment link, there is the ability to add custom dates for the subscription start date. However, there is not the ability to populate the subscription start date with the contents of a hubspot contacts date field.
We process applicants in advance of their contractual start date, sometimes a year in advance, and we do not start their subscription until they start their contract - Its a different day for everyone, so we need the ability to start a subscription on a date that is known in a field in the associated contact.
They would be applying through a membership page in Hubspot CMS, so there wouldnt be a problem in them clicking a payment link and hubspot pulling through this field, as they are logged in and we know who it is.
