Indent Footnote text (between the raised number and the body text)?

How to indent Footnote text (between the raised number and the body text) automatically?

I have word 2013, and I would like to insert an indentation 1.5 between the raised number and the text in footnotes (see figure 1)

Figure 1
¹xxxxxxxxxxxxxxx
²xxxxxxxxxxxxxxx
³xxxxxxxxxxxxxxx

When I go to "Footnote Text" style, and then paragraph to do the indentation, it moves the number and the text to the right (see figure 2). But I do not want this.

Figure 2

¹xxxxxxxxxxxxxxx

²xxxxxxxxxxxxxxx

³xxxxxxxxxxxxxxx

If I use the hanging option, it only indents the texts below the first line (see figure 3)

Figure 3
¹xxxxxxxxxx

xxxxxxxxxx

I have gone to "Footnote Reference" style, but the "paragraph" tab is locked. I cannot enter. Can anybody help me how to unlock it? Alternatively, how can I get the results I want (figure 1)

Thanks, M.

Create your own style, based on Footnote.

I have my own style based on footnote. How can I access the "paragraph" tab in Footnote Reference style. How can I get the indentation as shown in figure 1? Can you please give details?
