figure numbering

[Jonathan Ware]

Hello,

Is it possible to label figures in lyx so that (for example) those under
a paragraph heading are numbered <<paragraph number>>-<<figure number>>
(e.g. 2.3.4.1-1), those under a subsection heading are numbered
<<subsection number>>-<<figure number>> (e.g. 2.3-2) and so on?

Thanks in advance for any help.

Jonathan
