One-time compensation enabled for timeframe type reports

Hi team!
Just a quick question - I was checking out the API to see if anything like this was foreseen, but couldn't find anything.

I need to create reports (monthly timeframe) with employee salaries - and that should include as well data on their one-time compensation (e.g. bonus or sales commission) for that month. At the moment the one-time compensation can be viewed only for "point in time" reports - is there any plan to add this column for custom reports over timeframes, to have a complete overview besides fix salary?

Thanks in advance!

Cheers,

Sven
