Hi Lando,
I'm interested in this approach, but I haven't been able to find any advice that definitively allows plan sponsors to do this. The closest I can find is an auto sweep, where the plan sponsor can auto enroll any participant that is contributing less than the default automatic enrollment date. It seems like most participants who are under contributing would be more receptive to slowly increasing their contribution rate, rather than just boosting it up to a set rate. Were you able to find out any more on this subject?
Thanks
