e.g. product purchase on payment plan + bump order for subscription

Currently it is only possible to have one recurring payment when checking out.

Scenario: A client chooses to pay a product via payment plan with lets say 2 or 3 installments instead of one upfront payment. Since this is qualified as a "recurring" payment, the client can't pick an additional order (bump order) anymore if it is based on a recurring monthly payment (e.g. membership or subscription).
