Using Tiered Numbers in a contract document

I am hoping that there is a way to reference a tiered number within a document, such that if the tiered number is altered, then the reference to it is also altered.

For example, I am involved in writing a contract that has content which references other clauses. If sections are added or removed, then the tiered numbers update, but so far this means I have to go through the document, find every reference to a clause, and manually change it.

Is there a way to make a reference and have it change automatically if the tiered number it is pointing to is changed?

An example:

2.3 Nothing in clause 1.7 shall be considered to be in conflict with this clause 2.3

Now... if I add something before clause 1.7, the tiered numbers change... but I want the text which references those to also change.
