For the life of me, I cannot figure out how to reference multiple items in a list at one time. Assuming a list"

1 Bla Bla Bla
a. line 1
b. line b
c. line c
d. line d

Now, to reference items 1.a to 1.c, the reference should read as: 1a..c Now, I cannot figure out how to do that in word without going through multiple steps. Word will not let me select 1.a to 1.c at one time. I can create this type of reference in LaTeX in one step.

Can anyone help me with this?
