I Need My task Id ( Mentioned in Commit Message ) as a Link to my task System

[rsharma02@xento.com]

For this I am Using Repository Settings->link 

But when I am using TaskId with more than 6 digit my Regex is not working then & It will redirects me to 

https://bitbucket.org/<WorkspaceName>/<RepoName>/commits/<TaskId>

Expected is It should redirected me to my custom link.

(With 6 digit of Task Id it works fine, Also in regex I was used {6,9} But it also not works)
