Automatic application of ul/ol tags upon conversion

I wanted to ask whether it was possible to have a style (list) that would automatically map an already existing list in a Word document to an HTML (ol/ul/li) list upon conversion.  In other words, if I have a numbered list in Word as follows:

Fruits

1. Apples
2. Pears
3. Peaches

Could I now convert that to HTML within RoboHelp with a CSS that matches the corresponding Word style and receive an ol/li list?

I know that I can easily apply a list style from RoboHelp; however, there are a number of Word documents to convert and many have a list style as follows:

Fruits

1. Apples
2. Pears
3. Peaches

Citrus Fruits

1. Oranges
2. Grapefruit

With the marked difference being that Oranges and Grapefruits are numbered four and five respectively, instead of one and two.  This means that I have to start the list numbering at another number at appropriate intervals.

Any assistance on this is much appreciated.  I am using RoboHelp 10 and outputting to Web Help.
