Hello Anu,
I have a solution for this, but the better way is to just import file without ordered (numbered) list and then make list inside of the InDesign.
Just follow the steps:
1.Choose “Type Tool”, select the lines or paragraphs that you want to apply numbered list to.And click on the numbered list button in the control panel.The great thing about numbered lists is that you could update them very easily.
2.Select all the paragraphs, open up paragraph style panel, and make new paragraph style and for example call it “level 1” and be sure that you selected “Apply Style to Selection” check box.And click OK.List is messed up, but don’t worry.
3.Double click at style you made before.At the left click a Bullets and Numbering to open up that pane.In the Numbering Style place you need to change “Mode” to “Continiue from previous number”.And now the list is ok.
4.Select the paragraphs that you want to be the second level numbered.Again, go to Paragraph Styles panel and make another style called level 2 and be sure that you selected “Apply Style to Selection” check box.Go to Bullets and Numbering again, and at the Level textbox choose number two.And then you can change Format,Number(code), and the part that is most related to your question is position.You can just increase Left Indent and that’s it.
Note:If you want to make another level you just keep making paragraph style and keep changing level textbox.
