Action Assignment Block in SRVR

Dear Champs,

I am willing for using ACTION Assignment Block in Service Request (SRVR). Initially, I could not find any ACTION Assignment Block through Personalize option . Then I click on configure page and from there Move Action Profile Assignment Block in to Displayed Assignment Block Option (See screen Short 1) . But after saving that configuration I can not find ACTION Assignment Block in Personalization (See screen short 2).

Please guide me how I can get Action Assignment Block ?

Looking forward for your cooperation.

Thanks
