Excel Export with template

I suggest to implement the following feature:

When exporting to Exel, I would like to be able to select a template file xltx or xltm in which, for example, formatting and calculations are stored. In the best case, even macros that are started automatically after the export.

A typical use case might be:

We have an evaluation of working times in which relatively complex calculations take place and the entire data is then portioned again with a macro for different user groups. To realise this with a separate L&L report is time-consuming and error-prone, as a change has to be made in 4-5 reports.
