Help me with WPI (FMX)

[Spotless]

Hey I'm recently working on a project that installs Software instead of Games
So whatever...
Is it possible to Add a Size label next to ''Software List'' when Selecting every component,
and When selecting all components, I want it to change this

to the Calculated size
If there is any another opinion you can tell

Script Download Link

(It's like an Autorun of a Game but installs software silently by CMD commands after extract).

Thanks!

Waiting....
