Node name change with coral multifield in AEM 6.4

Hi All,

In 6.1, we customized multifield nodes to be saved as a particular name like slides-1, slides-2 etc. using following xml snippet.

<slides

    jcr:primaryType="nt:unstructured"

    sling:resourceType="granite/ui/components/foundation/form/multifield"

    class="list-option-carouselType-showhide-target full-width"

    eaem-nested=""

    fieldLabel=“Slides”

    showhidetargetvalue="[basic,large]">

    <field

        jcr:primaryType="nt:unstructured"

        sling:resourceType="granite/ui/components/foundation/form/fieldset"

        name="./slides-$">

However for 6.4 to have rich text work with multifield, I needed to use coral multifield resource type and following xml snippet.

                                    <slides

                                        jcr:primaryType="nt:unstructured"

                                        sling:resourceType="granite/ui/components/coral/foundation/form/multifield"

                                        composite="{Boolean}true"

                                        class="list-option-carouselType-showhide-target full-width"

                                        eaem-nested=""

                                        fieldLabel="Slides"

                                        showhidetargetvalue="[basic,large]">

                                        <field

                                            jcr:primaryType="nt:unstructured"

                                            sling:resourceType="granite/ui/components/foundation/form/fieldset"

                                            name="./slides">

Here multifield nodes are saved as item0, item1 etc. under jcr:content/slides.

Can anyone let me know with 6.4 coral multifield, how can we have custom multifield names like slides-1, slides-2, etc. instead of item0, item1, etc.

Thanks
