Using customer acceptance only for some lines of a sales order

Hi Practitioners,

We have a requirement to use customer acceptance on ad-hoc basis. Users would want to manually select customer acceptance on sales order line level.

1st question: If FIN team is defining a contingency rule, acceptance is always getting populated on sales order line level and then we have to remove it manually whenever we don't want it, which is obviously a cumbersome task. We can do form personalization but checking if there is any other option to use CA on ad-hoc basis on some order lines and others not.

We thought of having a new order type specifically for customer acceptance orders but that's not acceptable by business.
