python-singlespec - how to deal with scripts

Hi, I need some advise on how to deal with scrpits that come with a python package and are inteded to end up in %{_bindir} The package in question - python-relatorio 0.10.0 - is build for python2 and 3 1) How to deal with the shebang in the script, which is currently /usr/bin/env python ? 2) how to call the %files section properly? %{_bindir}/relatorio-render causes the rpm check to fail as it is packed three times (for python36, 38 and 39) %python_for_executables %{_bindir}/relatorio-render throws an error as well...... Hints welcome.....thank you!
