Replace all one-digit number with two-digit numbers

I have a huge data that looks list like this:
10.2-1.11-10
10.3-1.3
10.5-23
100.10-1
100.1-2.2-2
100.12-1
100.5-7
100.6-17
100.6-17.1
100.7-3.11
100.8-1.2
100.8-2.22-5
100.8-2.23-17
100.8-7.5
160.2
160.3
20.3-1.2
20.3-1.3
20.8-1.1-10
I want to replace all one-digit number with two-digit numbers
I was trying to replace “.” With “.0” but then it changed the two-digits three-digits as well.
Then I tried to find “??.?-” and replace it with “??.0?- ” but it is replacing all the numbers with “?”
Can someone help me please?

I v been struggling with this for days!
I can make it on several phases if I only could make the Excel find “number number-" and replace it with “number number-0” Is there an expressions to represent a number?
