smh
you can do this yourself @lizchu413

go to home service and look for the post create / post update announcements functions

use replaceAll to find all urls in the announcement content and then swap with an a href in front of it

the regex is /[-a-zA-Z0-9@:%.+~#=]{1,256}.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%+.~#?&//=]*)/gi;
