At the moment we are using MC suppression lists to avoid emails being sent to a blacklist we have. The issue is that we would now like to have three different lists of emails to whom we should never send an email.
I guess suppression lists is not the way to go because in a Send Email event only one can be referenced, but I do not know for certain. Here below is where we reference it (in the Email Send configuration):
I would like to know how this use case is usually approached, or if there is any workaround for the given problem.
Thanks!

Get 'Auto Suppression Lists' enabled on your account on the Parent Business Unit.
Create an Auto Suppression list from Admin > Auto Suppression Lists. An ASL can be applied to various business units and/or send classifications. You can also create multiple ASL's
Add the your suppression records a data extension.
Include in your automation a file extract to extract the records from your DE to CSV and upload to Safehouse
Also include a step in your automation to then import from Safehouse the CSV file and Import into the Auto Suppression List.
The auto Suppression list works at Email Address level (not subscriber key) and is applied on every send (based in send classifications and business units).
If a contact appears in a data extension or list and has been added to the auto Suppression list then they will be automatically suppressed. You therefore don't need to manually add the suppression list to each send
