How to add tips to ticket

1.) It seems that Tips will be printed through the Discount line

[DISCOUNTS] {CALCULATION NAME} %{CALCULATION AMOUNT}|{CALCULATION TOTAL}

This causes some problems because on the docket it will print e.g.

Discount %12 -3.72
Tip %99 99

How do I get rid of the “%99” on the Tip line yet still keep the Discount in place? See images below



2.) In this country tips are not taxed. **How do I stop Tips being counted towards tax?** If I enable "Include Tax" setting for tip calculation type the Tip line for some reason will not be printed anymore ...?

3.) How can I get the Tip text to align with the Ticket Total and Tax Total? There is no spacing before it in the setup. See image below


4.) Is it possible to assign a waiter to each Tip for the reports? I know how to display a user on the ticket with {USER NAME} but how to allocation a certain User to a Tip in reports? Think of it like a little friendly competition between the staff and a way of increasing productivity (as long as they do not hassle the guests).
