Hey & welcome to GT!

Yes. Anyway you can find to play the notes required for the chord is fine. Gsus4 is:
G (1st)
C (4th)
D (5th)
Any place on the guitar you can play those notes together is a Gsus4!
However, I also encourage you to keep working on the more difficult voicings. The more options you are able to play, the better a guitarist & musician you will be.
Hope that helps!
