Unable to assign any "select next window" with a combination "hold" button shortcut that conflicts with another shortcut that shares an individual "hold" button

[phazei]

Describe the bug
The conflict checker checks to see if any individual "Hold" key exists somewhere else even if it's used in combination. If an individual key from combo "Hold" key is used individually in another shortcut, it fails.

Examples:
Suppose I use (⌥) + in shortcut one.
Then any other shortcut that uses (⌥+⌘)+ doesn't work

It happens with any individual "Hold" key.
For ex:
⇧ + J
Then I try
⇧⌥ + J, it gives a conflict error.

There is a work around currently:
unassign ⇧ + J
assign ⇧⌥ + J, no conflict
reassign ⇧ + J, no conflict

Then both of them work perfectly as expected.
