[SOLVED] How can I add mixed content to quotations?

Hi,

I would like to know if there is a way to add mixed content to a single quotation containing these lines for example:
1 fixed amount
10 days of work
5 other days of work
Another fixed amount

Currently I can't have many lines such as in invoices.

I guess that's not possible (yet?) but do you think of any workaround such as having a parent quotation containing subquotations?

Thank you,
