Keep Size Text while changing scale in layout

Hello

Is it possible for a quote to keep the size of the printed text while the scale of the layout is changing?

 

In drawings, I am confronted to this Problem:

The drawing has an averall layout and some details. In the averall Layout, I don't need to read the text of the details.

But in the Detail-Layout, I need a smaller text for the red quote.

Just have a look at the document attached.

In the sheet 1, I need to print the averall drawing and a detail of this.

You can see that the textsize of the big cercle in red is much too big for the scale 5:1. So I would like to keep it readable in this scale and in the 1:2 scale.

In the meantime, I don’t need to read the text of  the detail-drawing in the general-Layout.

 

Is there a function for keeping the printable size of the text  undependent from the scale of the layout ?

 

I hope you understand my problem, and I hope even more that there is a solution :)

 

Thanks and best regards.
