How to increment in the middle of a mask?

[thanxalot4urhelp]

How do I increment a single custom charset instead of the whole mask.

I am trying to crack passwords with the following mask:

• Start with one capital letter.
  
• Followed by 5 to 10 lower case letters.
  
• Followed by 2 to 4 decimal numbers.
  
• Ending with one exclamation (!) sign.
  

Translating to the following combination: Aaaaaa11! - Zzzzzzzzzzz9999!

I try doing this by creating custom charsets for the lower case letters and the decimal numbers, but for some reason it sets the increment option to the whole mask.

The command I use is:

Code:

hashcat -m [xxxx] [hashfile] -a 3 -1 ‘?l?l?l?l?l?l?l?l?l?l’ --increment --increment-min=5 --increment-max=10 -2 ‘?d?d?d?d’ --increment --increment-min=2 --increment-max=4 ‘?u?1?2!’

What am I doing wrong?
Or is this currently impossible with hashcat? If so, what would be the advised method to crack the mask listed above?
