Retain downloadable product after subscription is cancelled

I have a question regarding downloadable files that are released on on a schedule for a subscription product.

We have a situation where we are releasing a subscription product, and this subscription will include downloadable files released on a monthly schedule.

When a customer activates the subscription then we will use the “drip” release feature to only give the customer access to new content as it is released when their subscription is active.

However, the problem that I am running into is that when a subscription is canceled then that customer loses access to any of the downloadable content that they accrued during the time that their subscription was active. I want them to retain access to those downloads. I just don’t want them to gain access to any new files that are released after the subscription is canceled.

Does this make sense?

Essentially, anytime that the customer has an active subscription and a new downloadable file becomes available for that subscription product then I want to give them access to that file, and retain access to that downloadable file for ALL TIME regardless of whether they cancel their subscription at a later date or not.

Is there a way to do this?

Thanks for your help!

Best Regards, and Happy Holidays! ??
