A small metal bobble on the outside of the door engages with this latch
I am trying to work out which design organisation (21J) can do this mod as the FLM supp is missing I think maybe AAT but any help appreciated

Just read your post properly - oops - try. this.
There is also AHUK-135-0023 STC for a longer strut that increases the door opening on the CP side by about 180 mm.
If it's only for maintenance it is fairly common practice to knock both front gas struts off and tie both doors open together with a bit of rope and padding on the pitot tube mount. You would be brave to turn blades with the doors in this position. EC120 has a little issue with this as a few have found when in a strong tail wind on the ground with rotors turning and you open the RH door and the strut lets go. Very expensive.
