Enhancement for readingDefinitions in 98_CustomReadings.pm

[gbomacfly]

This is a feature request for an enhancement in 98_CustomReadings.pm

For a better use of readingDefinitions I would like to use attr WEB JavaScripts codemirror/fhem_codemirror.js

In order to do this, the following line should be extended: https://github.com/mhop/fhem-mirror/blob/495c82aabe8953a887a9fac588f51e9de8048efa/fhem/FHEM/98_CustomReadings.pm#L19

into $hash->{AttrList} = "readingDefinitions:textField-long "

Would this be possible? Thanks in advance :)
