The simplest way might be to open a new pcb then place the fastons where you want them them save that as a PCB Module. Another way is to clone the faston PCB  Footprint then open it for editing and then copy and paste the faston footprint into each of the required locations, giving each a unique,  sequential pin number. Then save that new footprint with the same name as the relay symbol to which you want to assign it, as suggested in (2.3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) [71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a). which will give more info about symbols and footprints.

@andyfierman I'm going "clone" approach now, but it is very inconvenient, as I can not group elements of one "smaller" footprint into one object. It is very easy to move these parts independently and it is very hard to place them in exactly needed place: I can not select them together and set same X/Y position, as it moves parts of one footprint relative to each other...

The PCB Module option might be better. If you are careful with how you edit the json file header information, you can probably create your PCB Module and then edit it the EasyEDA Source file to convert it to a PCB Footprint file. Open a blank PCB Module and a new PCB Footprint and carefully compare the two json files. Then add something to each file and compare again. :)
