Is this possible? (multiple ion-router-outlet)

I’ve got a main router-outlet in app-component and then, another router-outlet named inside one page that is loaded inside the main router. When I tried to load, from this page, another one in the secondary router I receive and error ‘cannot match any route’. I’ve tried writing the route in the app-routing and manage.module.

I think the easiest way to explain my issue is showing all the code:

app-component.html

<ion-app>
    <ion-split-pane>
        <ion-menu contentId="primary">
            <ion-header>
                <ion-toolbar color="primary">
                    <ion-title>Menú</ion-title>
                </ion-toolbar>
            </ion-header>

            <ion-content>
                <ion-list>
                    <ion-menu-toggle auto-hide="false" *ngFor="let p of pages">
                        <app-menu-item [page]="p"></app-menu-item>
                    </ion-menu-toggle>
                </ion-list>
            </ion-content>

            <ion-footer>
                <ion-toolbar color="primary">
                    <ion-title>Salir</ion-title>
                </ion-toolbar>
            </ion-footer>
        </ion-menu>
        <ion-router-outlet id="primary" main></ion-router-outlet>
    </ion-split-pane>
</ion-app>

manage.page.html

<app-header-manage></app-header-manage>

<ion-content>
    <ion-router-outlet name="manage"></ion-router-outlet>
</ion-content>

header-manage.component.html

<app-header [title]="title"></app-header>

<ion-toolbar>
    <div class="tabSliderHeader">
        <div class="tabSliderWrapper" toggleScroll="hideScroll">
            <div [routerLink]="['companies/list']" class="headerTabSelected">Clientes</div>
            <div class="headerTab">Proveedores</div>
            <div class="headerTab">Agentes</div>
            <div class="headerTab">Artículos</div>
