Yes the easiest way is by direct dripping two or three drops onto the atomizer bridge, and puffing as usual. When you want to change, just drip the new flavour, and carry on. There may be a period when you get a mix of the two, but if you carry on with the new flavour it will eventually take over.
Just a hint though, if you have any really powerful flavours in your selection, these can stay in the atomizer for some time even when you put a new flavour in. Some people dedicate an atomizer to
tobacco's, one to menthols, one to fruits, one to coffee's and so on. Things like strong menthol, and strong coffee can stay in the atomizer for a long time after you've stopped using the flavour, so this makes
sense!
