Add your another form (your previous subform of your previous main form) into same unbound form as second continuous subform. Instead of linking it to PK of your another form, link it to hidden unbound text box in unbound form.
In case you need several forms to be linked to your now continous main form, and it will be crowded in unbound form, you can have a tab control in your unbound form, and place all forms (or all linked subforms) into pages of this tab control.
