Is there a way for scanning the stocks like this?

i want to scan the stocks which are added in my watch list or my custom stocks list which i created for trading.
for example say, i want to scan my selected specific 100 stocks only for the set of patterns in them or for any particular type of strategy. can i do this, can i scan the stocks , not all stocks but my selected stocks for the specific set of chart patterns in them, if yes, please advise. thanks
