I believe you can log experience time now, you don’t have to hold any qualifications to gain experience, it just has to be gained within a certain timeframe of licence application.

six months of observation of base maintenance tasks.
(b) An applicant for an extension to an aircraft maintenance licence shall have a minimum civil aircraft maintenance

28.11.2003 EN Official Journal of the European Union L 315/75
(d) For all applicants, at least one year of the required experience must be recent maintenance experience on aircraft of
the category/subcategory for which the initial aircraft maintenance licence is sought. For subsequent category/subcategory
additions to an existing aircraft maintenance licence, the additional recent maintenance experience required
may be less than one year, but must be at least three months. The required experience must be dependent upon the
difference between the licence category/subcategory held and applied for. Such additional experience must be typical
of the new licence category/subcategory sought.
(e) Notwithstanding paragraph (a), aircraft maintenance experience gained outside a civil aircraft maintenance environment
shall be accepted when such maintenance is equivalent to that required by this Part as established by the
competent authority. Additional experience of civil aircraft maintenance shall, however, be required to ensure understanding
of the civil aircraft maintenance environment.
