Increase Number of Recent Applications In Dock

I've enabled the 'Recent Applications' folder to appear in my dock:

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'

Is there any way to increase the number from 10 Recent Applications to 15, or preferably, omit specific applications from being in it.
