1050 DMs may not be enough, for my use case.

based on answer to another question that even manual replies we may make to our Insta DMs will count towards the 1050 monthly limit and if that is exhausted we need to wait for account to reset, could imply no manual replies also possible on my instagram DM.

So I am wondering if I can buy two deals of 3 tiers each and activate them together to have a limit of 2100 DMs a month?
