It should be possible to choose if a Form updates Opt-outs (only Opt-ins) when used as subscription forms.

Currently Forms always update consent, if added onto the form - either as opt-in or opt-out.

Example:

We have setup preference centers with topics like; Newsletters, Event invitations, Surveys.

These are options that an end user can subscribe to from our website.

Person A subscribes to topic: Newsletters on the Form on our website.

Their contact point consent will update as follows: Newsletters Opt-in, Event invitations Opt-out, Surveys Opt-out.

A moment later, they decide to also subscribe to Event invitations and navigate back, selects only Event invitations (because on the previous submit). Their contact point consent will update as follows; Newsletters Opt-out, Event invitations Opt-in, Surveys Opt-out.

Also, there might be scenarios where on Forms we would like to promote our newsletters "You might be interested in our monthly newsletters in following topics; A, B, C". But this is now impossible, because even if the end customer had previously subscripbed to one of these topics, new Form submit will set these topics to Opt-out (if not always manually opted in on forms).

To me, Opt-outs should always happen in Subscription Center/ Preference Center forms, where End user can actually see their current selection. If this is not the case for everybody, it should at least be a selection on the Form whether it updates Opt-outs or not.
