You can use CMS.Controls.CMSControlsHelper.SetFilter method in your master page to set the control to RequestStockHelper (you can find sample code for this method in SetupControl method of ~\CMSWebParts\Viewers\BasicRepeater.ascx.cs file) and then in your aspx template you can use CMS.Controls.CMSControlsHelper.GetFilter method to get the control from RequestStockHelper. Please see example bellow:

1) put following code into master page:
<asp:Literal ID="litCurrentSection" runat="server" Visible="false"></asp:Literal>

2) put following code into page_load method of master page:
litCurrentSection.Text = "Test";
CMS.Controls.CMSControlsHelper.SetFilter("litCurrentSectionTest", litCurrentSection);

3) Put following code into Page_Load method of your aspx template:
Literal testLiteral = CMSControlsHelper.GetFilter("litCurrentSectionTest") as Literal;

and check value of its Text property. It should contain "Test".
