Is it possible to remove Agumon from front line (battle lineup)?

Question for Digimon World Data Squad

Is it possible to remove Agumon from front line (battle lineup)? I’m just curious if you can put Falcomon in it's place. My reason is that I want to save leveling up Agumon until Creepymon is unlocked with the abilities of “level up” for every stat (under the abilities tab next to the requirements tab) to max out all of it's stats with out cheating. I also plan to do that for Renamon and Biyomon assuming they have megas with more “level up” stats than Falcomon, Goagamon, or Lalamon since each of these three only have “level up” stat for one and only 2 for Lalamon having Lucemon. Side note that you need to have that form on to benefit from these increased stats- I tested having Agumon level 13 leveling up with Geogreymon (which has “level up str” ability) having 241 str and leveled up to level 14 which got to 260 str. Then I went back to load the file and try on two other champion levels to see if it was only like 1 stat point. When I leveled up again on Growlmon and regular Greymon (then I would swapped back to Geogreymon since those stats would differ slightly) Geogreymon only had 252 and 251 str from those level ups respectively. Finally I went back a fourth time (to double check) and leveled up as Geogreymon a second time and had 258 str so 6-9 in every stat every level would be much better by the time it got to level 60 being anywhere from 300-450 extra in every stat would be pretty nice.
