Transfer labels from leads to deals

Hi all,

It would be great if we could transfer labels from leads to deals. This way every time you assign a specific label to a lead, that label would then stick to deal coming from the lead, which can be pretty useful, especially if you want to keep track of the lead funnel: where it came from, and what type of deal it ended up being.

The use case:  when a lead is coming from marketing I assign the "Marketing lead" label and then I want to keep such label when the lead becomes a deal, so I can evaluate if marketing activities are creating quality leads or not.

Thanks!
