Stripe Description for Subscription Charges

Hi Everyone,
My form is successfully posting to Stripe. It is setup as a subscription and I want to change the description of the payment in Stripe to reflect what the user inputs into a field on the form. Right now it displays some random invoice number. Any pointers?

I looked at gform_stripe_charge_description but I think it only works for ‘product and services’ feeds.

Thanks!
Adam
