Saving to a gif format and choosing the color palette

[SpongeBob]

Hello people,

I'm still running under my "old" photoshop CS6 but I plan to quit adobe because of their policy since the cloud based version....

So in photoshop when we saving a file under a Gif (for web) we have the possibility to chose witch color will remain or be deleted etc.. is their anyway to do the sane under gimp 2 ?



Thank you
