modify lisp to link selected blocks with nearest block

[jtm2020hyo]

First request:

Attached lisp request a select a block to create a link with the nearest point. but all block with the same name is automatically linked to their nearest block

what I request is to modify this attached lisp-routine to work just in selected blocks/dynamic-blocks (no all blocks with the same name) 

Second Request:

Attached lisp allow just link with the nearest block with above 180 grades ( since 0 grades to 180 grades relative in each rotation block individually ). 

What I need is to convert that 180 grade allowed to 2 variables or 1 range that can be modifiable for the user. (default since 0 grades to 180 grades)

Image explain better how this lisp work actually

But for second point what should be the reference point for measuring angle........

But show me your workout First .....

[jtm2020hyo]

until now, your lisp-routine work perfectly.

thanks for the help.

the first request was solved.

0 sexagesimal degrees as center (for 180° = 90° until -90°)
