Being able to customize it with a prefix and/or suffix (or none) is a good idea.
Without a suffix, we'll have : xxxxx 1, xxxx 2
With a custom prefix like V. : xxxxx V.1, xxxx V.2
With a custom suffix, C for example: xxxx 1 C
I'll add to that the ability to use %variable like we already have now. So someone could add a %date or %time as a suffix
Timeline, with the prefix "V.", the suffix "- %currenttime%", would make : Timeline V.1 - 10:20:05

<< as we have here, when someone starts with %, it gives a list of variable that can be used.
I don't see current time and current date, so it should be added in the general list
