SLA information on request

SLA information on request

Hi,
 
Can anyone help me with adding a custom field on the request which shows the SLA that would be assigned to a specific request?  These are allocated through automation, but it would be useful to see within the actual request, which SLA applies...
 
Hope I've made myself clear... just want to be able to open the request and see what SLA is assigned to it.
 
Thanks
 
(relatively new user ;-)
