If yes, how ?
If not, is there a workaround to get similar functionality ?
EDIT:
What I mean is something like this :
// TODO line1
// line2
// line3
and line1, line2, line3 belong to the same TODO
and get highlighted with blue.
This is supported since 2018.3.
Multiline TODO comments
IntelliJ IDEA 2018.3 now supports multiline TODO comments, now the first and all subsequent TODO comment lines are highlighted in the editor and listed in the TODO Tool Window. Simply add an indent starting from the second line of your multiline TODO comment, and the IDE will differentiate it from an ordinary comment.
