First line auto indent according to font size

[Yichuang驿窗]

In the style manager, I can set the first line indent value in the properties of the default paragraph style.

But, if I made a custom paragraph style from the default style, and modify font size, the indent value is not suitable. For example, if the custom style's font size was larger, the indent value remains the same, it would be too small for me.

This result does not like LibreOffice Writer, in Writer it can automatically modify the indent value  to fit font size.

Is there a way to set auto indent in Scribus?
