Visibility Parameters containing attributes within Dynamic Blocks

[NBC]

Is it possible for a dynamic block to have one attribute which is set to different visibility parameters;

eg. i have a block made for a Setting Out Point. I wish to have 4 different locations that the user can place the attribute after insertion of the block ie top, bottom, left, right, of the SOP.

 

Is this possible in any way, shape or form ?

 

I have attached as far as I can go so far.

 

All ideas appreciated:

SOP-temp.dwg

I have had further time to look at this now.

For those interested, I think I have achieved what I initially set out to.

 

If anyone has other ideas of how to achieve my aim, please feel free to reply here.

 

My updated block is now attached:

SOP-temp-updated.dwg
