Scaling components by changing values in the info box

Is there a way to control the “anchor” point when scaling a component by changing the values in the info box? Let’s say I want to make the marks in my /quotedbl, which is comprised of two /quotesingle components, a little smaller. I can click on each and change the 100% to, say 95%, but doing so moves the mark quite a bit so I have to realign with the /quotesingle by hand. It appears to assume the scaling should be relative to the point of origin of the original glyph? It would be handy if I could choose a transformation origin when scaling components this way (for ex., if it respected the last chosen spot in the “grid” for that letter, or the last origin point chosen with the scale tool, or whatever setting is current in the Transformation palette).

I have a look at it…
