what do you mean by group formation? Be a bit more specific.

[Actimel]

For example, line formation charge ny 5-6 cav units

[totalwar_legend]

So do you mean have them all charge whilst remained in a straight line with a single click?
If that's the case then no. Units charge to targets, not on command. The closest you could achieve this is group them up and then have them targeted to run directly through the enemy. As they're getting close you pause and select which unit charges an the enemy you want it to.

K, thank you

If you group multiple units (and there are enemy units that are relatively close by) and then command the entire group to attack any nearby enemy unit, then your units will auto-target the closest enemy unit. This is the best you can do to have your line charge by a single command. If the enemy's battle line is all neat and well formed (and is close to your line), this method will result in a relatively organized charge. If the enemy's units are scattered around, this method will result in a relatively disorganized maneuver.
