I am new to the scanner business, sounds like fun

I can’t find a way to enter frequencies directly into the radio. The only way to enter a frequency is to first enter the frequency into the scanners channel bank.
Is there a way on most radio scanners to directly enter a frequency (say Perth Tower 120.500) with out having to enter the frequency into a channel bank?
I have a Uniden UBC73XLT scanner.
Thanks for you help.
Giles.
