Hi
Is it possible to have to import a CSV to define the audience of an engagement? Or a workaround for this?
Use case: The users in PX are created the first time they log into our platform, and we have several FTUs engagements for them.
We need to target them with an engagement with a Dialogue but one Engagement should exclude some users based on some attributes. As such, we can’t define the “is not” part of the audience within the platform because the users do not exist in PX, but we can source them from Salesforce.
Currently we are exporting the report to a sheet file with a Fx to concatenate the addresses, copy paste from that concatenated cell and define the audience that way. Also, this is limited to x1000 emails, so when that threshold is surpassed, a new step in the audience is needed.

We have in the roadmap different FTU engagements according to roles and other criteria, so maintain daily 10x engagements this way is unsustainable.
Is there a better way to achieve this use case?
Thank you,
