Mask that contains streetname

Hello,

Where I live, very often people put their street name in the WPA password.

If for example my street name is "Longstreet" and I want to mask like this:

Longstreet%a%a%a%a%a

How to do that?

Additionally, can I have something like

%a[L/l]ongstreet%a%a%a%a (also prefix + both capital and small first character)

Or even something like %a%a%a%a%a%a%a%a%a%a%a AND 'contains Longstreet'.

Is there any way do to these types of masks using builtin features and without building a huge wordlist?
