You could use two instances of hashcat, where the first one generates candidates up to the 30 unique characters with a mask and pipe them into a second instance, which does the actual cracking and applies the rule to duplicate the last character 10 times.
Unfortunately this will probably not be of any good use for you, since this will not crack within your live time. Brute-Forcing 30 positions even with such a reduced char set is not be feasible, regardless of your hardware and the target hash type.
