Eficient ways to Move a guide?

Hi guys,

1) Is there any way in Photoshop to know the exact location of an existing guide like you can easily do in Illustrator and Indesign by watching the info box?

2) Besides that, can i move it to an exact parameter too like i do in Illustrator and Indesign? those are very helpful tips to the workflow.

Maybe there is a plugin to do it more efficiently. Nowdays, i have to always Create New Guide. If i like the New Guide 20 px from another guide and have to always remember the previous location or do the math...it too much time consuming. It would be great to have a box where i could put the value and move guides around like Illustrator.

Thanks for any help,

S.-
