AutoCAD Civil 3D :: How To Assign A Set Of Points A Sequence Of Point Numbers

What I wish to do is to assign a set of points a sequence of point numbers (or custom properties) of my choosing. For example, I have the following points:

100

102

104

105

107

I wish to assign point 100 -> 1000, 105 to 1001, 107 to 1002, 104 -> 1003, and 102 ->1004. Basically, I am looking for a command or utility that implements the "TCOUNT" (using select-order) command, but for Cogo points instead of text. The renumber points command appears to only work with offsets, and does not eliminate gaps. I can sequence the points if I select the points I want, then copy them -> set duplicate points to sequence from the range I choose, but this does not allow for reordering of point numbers. I tried individually selecting them in the order I wanted, but didn't change the order in which they were numbered.

Alternatively, I can leave the point numbers the same, and assign a user defined property that I can use to sequence the points in the order of my choosing. However, I'm not sure how to go about assigning the sequence I wish short of typing in each value individually; obviously non-ideal.

A third possibility that presented itself to me was to create new, correctly sequenced points that overlap exactly with the old ones, and then somehow merge the two sets together. Would there be a way to merge the old points and the new ones based on the fact that the two points have the same X-Y coordinates? Preferably done in CAD itself; the last resort would be to export both sets of points out to excel, then do some fancy manipulation in excel, then reimport into CAD.
