Well you can do something almost similar to that in Arcade Mode (Read Select.def for this) but you need a certain code for this to put it simply an open-source code from Elecbyte themselves but I don't see how that's going to work. But I'm going to put this here just incase it helps.
Spoiler: My Select.def (click to see content)
; - order
; Set the paramvalue to the ordering priority to give the
; character. Valid values are from 1 to 10. A smaller value
; means you will fight the character sooner. You will never
; fight an order 2 character before an order 1 character,
; and never an order 3 character before an order 2 one.
; For example, you might want to set your boss character
; to have order=3. The default order value is 1 if you omit
; this param. See *.maxmatches under [Options] for how to
; limit the number of matches per order priority
======================================================
[Options]
;Here you set the maximum number of matches to fight before game ends
;in Arcade Mode. The first number is the number of matches against
;characters with order=1, followed by order=2 and order=3 respectively.
;For example, for 4,3,1 you will fight up to 4 randomly-picked
;characters who have order=1, followed by 3 with order=2 and 1 with
;order=3.
arcade.maxmatches = 4,1,1,0,0,0,0,0,0,0
;Maximum number of matches to fight before game ends in Team Mode.
;Like arcade.maxmatches, but applies to Team Battle.
team.maxmatches = 4,1,0,0,0,0,0,0,0,0
