Insert plantisoaddinfo flow arrow on selected multiple pipe in autocad plant 3d.

[NiccoLo]

Good day. I'm wondering if it is possible to revise the command of inputting flow arrow on autocad plant 3d by using autolisp. The command is plantisoaddinfo then "A" and select pipe to be inputed. Is it possible to make it select multiple pipe and add flowarrow on selected pipe's center of gravity point XYZ or vise versa? I really appreciate your help. Thank you in advance.
