PAMM account delay open position. Is it possible??

 
Guys,

I'd like to ask.  Especially those of you who have experience with PAMM master/slave accounts.
 Is it possible for the master account to delay the open position for 30-45 minutes?

 The details are like this.
 Master is opening position sell at 06.00.  The master purposely hides this open positions so that the slave accounts cannot copy and reproduce master positions. Master then displays the open position at 06.30. After the sell position has been closed.

 Is this possible to do?

I am asking this question since I received EA offering that very suspicious.
