How to Remove and Add items in gallery. If items are split text.

Hi all, 


I have got a column that collects a text with a delimiter ",". And I wanted to put this into a gallery and show as an Items and control that particular collection using Gallery features such as Remove. And then keep the updated one. 


Here's an example case. 


I have got a text or Data  that looks like this - Autodesk Civil 3D,Autodesk Map,Autodesk Plant 3D


And I have used Split function in PowerApps which results as show below -


Used logic  Split(approvingrequest.X_x002d_NotRelevant,",")




I have taken this output as an item to my gallery. And I got something like this. and which is perfect.



Now my question is how would i Remove and Add these particular item and still be able to get back get all the new texts. 



Any help and workaround would be really appreciated. 


Thanks you
