Good day @LUVQVIST,

Thank you for posting to the PayPal community.

Merchant can able pass the custom value using the parameter as "custom" :

<input type="hidden" name="custom" value="SubscriptionName">

You can "Dynamically" pass different "custom" values.

If you have implemented latest Smart Subscriptions via REST API integration.

Please contact your website developer to pass the custom value as "custom_id" or "invoice_id" while performing the "Create Subscription API" call - https://developer.paypal.com/docs/api/subscriptions/v1/#subscriptions_create to PayPal system.

Sincerely,
