How to do Upgrades level tryllion +

Hi

First time on forum, english poor, so

I wont to make an upgrad that have no limi to improve.
For example : Mega Power Armor - level 10005 and so on.

in normal TFT editor i can set only constan max level upgrad, even if i will set 1 mln max level, there is a text describing the upgrade, wich i will have to tipe manual, and this is imposible.

Question is how to do infinity max upgrade level ?

rightclicking and using Auto Fill Levels works.

However, this is REALLY ugly, as an upgrade that big will take up so much space its not funny.
