Resize an object with grouped text boxes

[Jill]

Hello

I have designed an object using shapes and text boxes which I have grouped.
I have locked aspect ratio and need to resize (reduce the size of) the full object. When i do this, the font size remains the same as the original creation and therefore all wording gets cropped off. Is there a way for the font size to become smaller as you decrease the size?

I have tried copying and pasting the full object as a "Picture (Enhanced Metafile)" and then resizing but it doesn't look great as the font I presume gets converted to vectors

Any advice would be fantastic.

Thanks
