moving between desktop pages

hello

i love fences. i am using it since years! is the main reason why i am still working with windows!!

but now I have an issue

i used to have a mac air with parallels and win and to switch between desktop pages i used to "left+right mouse button drag"
i had never been able to use the other option probably for overlaping of functionalities with the MAc machine

now i have recently changed machine, I have now a mac book pro with parallels and win 10
with this new setting for some tricky reasons I can not use this option neither
the only my possibility is "alt + mousewheel"

so my question is.. is there any possibility to customize the way to switch between pages?
