Open more job files in different tabs

Is there a possibility to open more jobs.

I have a couple of costumers that needs parts cut but the by example the first time he needs 20 of part and 10 of part 2 etc. etc. but the sixth time he needs different quantity and or different parts from earlier jobs. no I can nest them every time but if there was/ is a solution to copy paste from different job files it will make it a lot easier and faster to make up the g-code
another question

is there a possibility to select multiply parts and give them all the same cutting operation .
now I select them one by one and give them the operation the need but,
mostly I have a job of about 15 or more different part but they all could have the same operation .
is there a faster way to do it
