On the purchase order option, is there any way to make the subscription stop after x months?

By the way on the purchase order option, is there any way to make the subscription stop after x months? Like I only want it to run 6 months which is what our plans are now.
And what about for a paid in full?
Since we offer both I wanted to list both but it only lets me do one or the other.

Since there is no payment involved with the Purchase order field on the form, it can be served only as a information capture. You'll be required to create a subscription on your payment gateway manually after receiving the submission or through the CRM if that works.

And what about for a paid in full?

Unfortunately, the number of payments is not an option with Purchase order field. It is only possible when you use the Auth.net payment field on the form to capture the payment.

Thanks!
