acoustic bridge help

I picked up a new guitar yesterday from my uncle.. Its a slighty smaller guitar...not really to noticable but it is alot easier for me to hold. The problem with this is the part where the strings go on the body of the guitar ( i do think it is called a bridge but i'm unsure) has the strings closer together than my other guitar..So switching between them is kinda difficult as well as trying to fingerpick with this guitar.. Is there any way I can change out the bridge to one that has a wider separation in the strings my like other one? Thanks for the help!
