From date - to date using workdays and linktoform?

[Linda_Marita_La]

I’m in need of a little help here.
I have a app where my workers register if they are sick or on vacation.
Its based on a spesific date registration.
Now they want a function to register from date and to date to spare registration time.

I now have a column for “date” witch i can use as “from date”.
Can i set up a virtual column to get the “to date”?

And how can i get one row pr. date for all the dates including from and to date in my data sheet? We ar not working weekends so i guess i have to use WORKDAY() in my expression somewhere. Is LINKTOFORM the way to do this?
