How can i hold a string or choir sound like a pad even though i release pressing the chord

I tried to use hold option on the FlexPhraser to automate the strings sound like pads, but its not giving the original/natural feel of the instrument like when i manually hold the chords with hand.

Go into the release envelope and stretch out the ending cube. It looks probably like a line mountain drawing.
