Sigil creates IDs in the Hn start tags automatically (e.g. with a merging).

Example sourcecode:
<h2>preface (preface.xhtml)
<h2>Chapter 1 (c01.xhtml)
<h3>1.1 (c01.xhtml)
<h3>1.2 (c01.xhtml)

Result:
<h2 id="sigil_toc_id_1"> (preface.xhtml)
<h2 id="sigil_toc_id_2"> (c01.xhtml)
<h3 id="sigil_toc_id_3"> (c01.xhtml)
<h3 id="sigil_toc_id_4"> (c01.xhtml)

I'm not in love with that pattern.

My wish is:
<h2 id="t-1">
<h2 id="t-2">
<h3 id="t-2-1">
<h3 id="t-2-2">

Is it possible to realize that pattern?

If not, how do you like my suggestion?
Of course, while generating the ids, it has to be checked by the software, if an ID exists already.

Thanks.
