Strength training total/split question

Hello everyone,

I know it might be a silly question but please bear with me as I am still new to this and googling didn't answer me.

What I've been doing is (2x lower 2x upper) a week (~30 min each)

Can I do (3x total a week) by simply combining a lower session and upper session (and doing them in one long session 3 times a week?) or does it absolutely have to be specific exercises that target both muscles?

I need to lose the remaining 20 pounds but no longer losing (working out for 2 years). I was told I need to do total body workout.

I use fitnessblender but they don't offer a lot of TOTAL BODY strength training workout, mostly lower/upper based.

If not, can you please advise me on a good source for a total body workout program as most I found online are split-based

Thanks a lot everyone in advance
