Any "Easy" way to keep 50+ Mega accounts "Active"?

Hello

Back in the early days of Mega I made...quite way too many accounts, as a semi data hoarder I try to take advantage of every free online storage I can get my hands on - but now things are getting a bit out of hand has I get mails almost every day that X account has been inactive for too long and I have to login it or risk to have it deleted.

So the TL;DR version is: Is there an easy way to keep 50+ Mega accounts active without manually login every so often?

Thanks.
