HI vaclavkrizek,
Thank you for your purchase.

Yes you can achieve this.

Create 2 employees and connect them with each of the location.

For the 1st employee which will be in the location A set the working hours for Monday and Tuesday.

For the 2nd employee which will be in the location B set the working hours for Friday,

Then use the CSS to hide the employee from the front end.

I can send you a code for CSS if you can send me the page where you have a booking form.

Best regards.

HI Michal,

Unfortunately the use case that you described below is not possible to add more locations to one employee. 

There is a workaround where you can make three same employees () with different emails(you can use same email by adding numbers for example if your client email address is [email protected] you can make more employees with same email adding numbers like [email protected],[email protected]... )

And then you can use ameliabooking shortcode and on front-end you can hide with CSS  dropdown with Employees and it will be shown just Location dropdown like you requested.

It would be great if you could suggest this feature on our features list here. We plan to follow our customers needs and implement the most requested features first.

You will see that there is an vote for the feature Option for employees to work on a multiple locations.

Best regards.
