Can You Change Maps In Garry's Mod Well In Game?

So my friends tell me to change the map after an hour of being on the same one. But after i change it they all leave because i have to kick them out in order to start another game to change the map. They all assume that i was done playing for some reason. But, Technically speaking, is there a way to change the map without going all the way back to the Main Menu?

changelevel <mapname> or map <mapname> in console

example:

map gm_flatgrass

I go with DatMeg

using the “map mapname” method will kick them. Use “changelevel mapname” to not kick them.

Okay.
