Isn't there some sort of third party app that you could use that would allow you to add that in? I am not really interested in doge itself, I like the coin because it is a fun one and memes all aside they have even helped the world with charities and supports and even sponsorships so I know how awesome it is, I even took part in paying for a nascar sponsorship back in the day.

However I am asking this for all the other major altcoins, freebitcoin is free bitcoin I get that but like I said before, it would have been awesome if you started to imitate from just bitcoin and moved to other coins because lets be honest bitcoin will be too expensive to give away even 1 satoshi in the future, so you should be considering an alternative or you would be forced to have 9 decimals, and honestly adding multiple coins sounds a lot more wanted then adding just a 9th decimal.
