Feature Request - Link Field for better managing

i am not sure if i am in right topic here.

it would be great if there one Link-Field where i could put one link by WorkItem. And could reach the Link from time entries. (via icon for example)
So we could manage external resources too. From Time Entries per one Work Item.

For example i have TODO Lists in Confluence for each WorkItem.
And need each time find the right TODO list for the Work Item from Time Entries.
Manage Notice by Time Entry.
Manage TODO List in Confluence.
Find every Project and manage both. Its hard when there are many topics every day to switch between them and manage.
