Adding a new date range selection

[lksstml]

First off, thanks for the nice library, saved us a lot of work!

This question / request is somewhat related to #358 and #228:
Our goal is to let the user select a new (group dependend) date range within the timeline by clicking twice (first click = start date, second click = end date).

We've implemented a basic version using onCanvasClick and then add a new item (with different styling) after the second click.
This kind of works, but feels a bit workaroundish since the handlers etc. will be different for this new "item" as well. It would probably be better to not use the items array, but rather have some kind of a group dependant timeline marker, which can have its own click handlers etc.

Is this already possible with the current version? I couldn't find a way to have a date range marker for a single group. If not: Do you have a good idea / starting point how to implement this feature with the current version of the library? Or what would you suggest?

@lksstml could you please provide a code sandbox of you implementation? maybe also some mockups for the expected behavior I am not sure I get the requested feature

@Ilaiwi I added a very basic sandbox demo over here
You can click inside the calendar to add a new item (first click = start date, second click = end date).

The idea behind this is to let the user select a new date range within the calendar. After selecting the range, the user should be provided with some sort of context menu to choose what to do with the selected range (e.g. to add a new booking request for the date range + group).

My initial question was mostly about if there is already a feature implemented to handle such things or if there is an intended way how to implement it. I think ideally we could use some kind of custom/interactive marker for this, to which we attach our own handlers etc.
The misuse of the items array feels somewhat wrong, because it's mostly about displaying the selected range correctly within the calender and not about adding a new item.
