Structure formula to show linked issues as a attribute field

[Lean Li]

Hi,

In the linked issues  field, I have information about commits related to the task in question.

I would like to group tasks in my Structure by commits, but the issue links field cannot be used as a grouping factor.

I tried to find a way to implement, for example, a formula that would write commits as attributes in a Formula field. Can anyone advise if this is possible and what the formula would be?

Are there other possible solutions?

In the Linked Issue field:  Commit values ​​(url) looks like this: - Commit 3045626, Commit 8574630, Commit 2074364

And I would want to have a Structure like this:

Commit 3045626

- Task 1

- Task 2

Commit 8574630

- Task 3

- Task 4

Commit 2074364

- Task 15

Thank you already in advance!

I am trying this formula, but it doesn't return any value:

issuelinks.filter($.type = "git link").map(if $.source = this: $.destination else: $.source)

Any ideas, on how to proceed?
