Can section 44ad and 44ada be used together ?

Hello Sir/Madam,

I have a professional income from Consulting services of about 45 Lakhs p.a.

In addition, I also have a side business where I have my own websites. I am selling ad spaces which give me income of about 60 Lakhs p.a.

Is it possible to use both Section 44ADA and 44AD together in the same IT Return ?
Or, is it advisable to start a new partnership firm to keep both accounts separate ?

Your expert advice would be highly appreciated.

Regards
