SFDC Campaign Filter
I'm attempting to change a trigger campaign to batch. We currently have a trigger that ignites once an individual is "added to a SFDC campaign". Since this trigger is not reliable (it's not always firing) we need to change this to a daily batch, but I have quickly realized none of the current filters will suffice:

1. 'Campaign was Requested': you cannot add a constraint explicitly stating only a SFDC campaign

2. 'Member of SFDC Campaign': there ins't a date constraint to only pull in prospects added in a certain time frame.

After coming across this post my suspicion was confirmed - there currently is no filter for 'was added to SFDC campaign' in MKTO. Does anyone have a work around or another way to thinking about this? Or am I just stuck with a trigger that only works 50% of the time?
Thanks in advance!
