If I have to add a substitute player on a lineup before the game start, it is suggested to tap on Game Start, first entry in GAME MNGR > LINEUP and choose the player from the PLAYERS LIST... ok, but

==> I don't want the stats recorded from this game to appear neither on his personnal stats or team stats or else. I want nothing to appear nowhere.
In our league, the same player may be used as a Sub player 5-8 times during the season with diferent teams, this is why I don't want any mixted stats along the way...

What is suggested in the first sentence is the wright way do it??... or should I create a new ID player... what would be the best issue

TIA

Misc -> Show Starting Lineup
Add new player set to batting = No

This will not add to team roster and therefore stats will not show under that team. Player stats will show under that player.

If you don't want the player's stats when subbing to show up on their player stats, then you will need to create a dummy player to use for subs. If the player's name is John Doe, add a new player named subJohn Doe to the lineup. Then you can keep stats separate for each player when they play on their regular team or when they are subbing for another team.

That's what I don't want.

Let say the name of the player is Player 1
If I create a new ID in the PLAYER LIST like Sub Player 1
Misc -> Show Starting Lineup
Add new player set to batting = No, whom would be sub Player 1

Should I understand I will get personal stats for all Sub Player 1 no matter which team they will have played during the season as a Sub and it will be a different stats from the real Player 1 since we have here 2 different ID

Along the season, if recorded that way, all players who would had played as a Sub Player (with the prefix Sub before their name, meaning new ID), I shall get stats of all the Sub players created, which stats won't have any effect on the team they would had played as a Sub Player, and I shall get their personal stats recorded because they have a personal ID ... OUF!

Would that be OK

Yes, sub player stats would not count towards regular stats because to iScore they are two different players.
