SH5 : single mission & multiple refuelings

[dmy]

Hi there :Kaleun_Salute:

Sorry for my english, I'm french.

I would like to create a single mission, something like a special cargo delivery from Germany to Japan.

But I have a few questions ...
Is it possible to have two or more refuelings during one mission, or should I instead create a campaign ?
And how to do to add a refueling rendez-vous in the mission editor ?

I searched the web but didn't find anything.

Thanks for any idea !
