Spritefont adjustments via spritesheet

Is there any way to make adjustments from the spritesheet level?

Example:

I have many instances of spritefont with different content on a layout.

How to make one of them visible, while others are invisible? Like a changing subtitles...

If I select spritefont I can only make changes to all of the instances on the layout at once... How to apply changes only to picked instance?

Give the spritefont object variables. Use these to pick instance.

I'm sorry for my insufficient knowledge of basic programming, but let's say I picked an instance using it's variable, than what?

Can You provide some basic example?

system on start of layout

spritefont if variable is 0 - spritefont set visible

AFAIR if you create a spritefont and after that apply adjustments, they'll only apply to the one you just created.

I've played around with the spritefont. Both of you are right. Thanks.
