Duplicate-repeat function

must have!! Duplicate-repeat function! like in cubase, Ctrl+D command, that duplicates the clip and sticks the duplicated part at the end of theclip, so that i can click Ctrl+D as many times as i want and make the duplicated clip as long as needed only by reclicking Ctrl+D

in Premier, if i need to duplicate-repeat a clip i have to hold Alt, copy the clip, drag it and align it to the end of the clip, which useally is not working well so i place it a little ahead and only after i try to stick it to the end of the clip, then i need to copy the two repeated clips and paste them at the end and so on, this is soooooo frustarating and time wasting, there must be a solution for this! please create an option like in Cubase, quick and simple and user friendly!
