Minor problem with Pier +value:toc+

Hi! Me again :) Don't worry, I have like bursts of different works. A couple of weeks with a project, then another week with another project, and so on. I have this situation. I have a Pier page where I DON'T have big titles '!' but perhaps '!!' or '!!!'. Suppose this example of a complete page: +value:toc+ !!This is a little title because I don't want big titles here Blah balh balh !!This is another title This page, will generate me a index like this: 0.1 This is a little title because I don't want big titles here 0.2 This is another title Now, the behaviour I would love is: only if there is NO ! in the page, but !!, don't start with 0.1 but with 1 and get something like this: 1 This is a little title because I don't want big titles here 2 This is another title The same if I only have !!! Now...is this doable? any tip where I can look in? class? method? piece of code? Thanks!!! Mariano
